BOTTLE-STOPPER.

T all whom it may concern:

Be it known that I, OREsTE DEL GUERRA, a subject of the King of England, residing in the city of Chicago, county of Cook, and

State of Illinois, have invented a new and useful Improvement in BottleStoppers, of which the following is a specification.

The object of my invention is to provide a Stopper which is adapted to be attached te 1o any ordinary bottle and which is so arranged that when the contents of the bottle has been emptied the bottle cannot be reiilled unless supplied with the proper appliances, by means of which the bottle may be refilled. With the above and various other objects in view, which will be plainly evident as the description proceeds, the invention consists in the novel construction and arrangement of parts, which will new be more fully described 2o and claimed, reference being had to the accompanying drawings, forming a part of this specification, in which- Figure 1 is a side elevation of my im roved bottle-stopper in position in the nec of a 2 5 bottle, Which is shown in section. Fig. 2 is a vertical section of same, showing the plunger in position to prevent the refilling of the bo ttle. Fig. 3 is a vertical section showing the position of the plunger when the contents of 3o the bottle is being emptied, and Fig. 4 is a cross-section on line 4 4 of Fig. 2.

As shown in the drawings, the numeral 1 indicates the bottle-stopper, which is constructed of metal or other suitable Inaterial,

3 5 and 2 indicates the neck of a bottle.

3 indicates the outside casing of the stopper, the upper end of which is provided with the flan e 4. When the stepper 1 is in position in t e neck of the bottle 2, the ilange 4 is 4o adapted to be crimped around the top 5 of the ottle 2, thus rigidly holding the stopper 1 in osition.

6 indicates the inner casing, which is provided on the outer surface thereof with a se- 4 5 ries of spiral corrugations 7. Near the lower end of the casing 6 are openings 8. The channels 12,formed by the spiral corrugations 7, lead into those openings. When the inner casing 6 is secured in the outside casing 8, the 5o spiral corrugations 7 on the outer surface of t e inner easing 6 will rest against the inner surface of the outer casing 3. The lower end of the inner casin 6 is rigidly secured to the outer casing 3. plunger 9 operates in the Patented Aug. 21, 190B.

inner casing 6 and is provided with the con- Vex disk l() on the upper end thereof. The plunger 9 is adapted to operate in the inner easing 6 and is prevented from falling out oi said casing by reason of the iianges l1 on the upper and lower ends of the inner casing 6.

From the foreroing description it will be apparent that w ien the stopper is in position von a bottle the contents thereofl can easily be emptied.

I/Vhen the stopper is in position upon a bottle, as shown in Fig. 2, no liquid can be forced into the bottle, as the plunger 9 closes the opening on the lower end of the inner casing 6. In order to fill the bottle with liquid, it is necessary to employ a powerful magnet. When the neck of the bottle is placed a short distance below the magnet, on account of the magnetic attraction the plunger 6 will be drawn upward until it assumes the position as shown in dotted lines in Fi 2. This causes the plunger 9 to be raise above the opening 8, and when liquid is poured into the top of the bottle same will flow through the channels 12 into the openinfr 8 and then into the bottle. The wp of the isk 1o is Convexshaped and ease-hardened steel and so arranged that unauthorized persons could not raise the plunger 9, and thus ill the bottle. When it is desired to empty the contents of the bottle, by turning the neck of the bottle downward the plunger 9 will move downward, as shown in Fig. 3, and the contents thereof will flow through the opening 8 and out throu h the channels 12. i

Slight c langes can ofcourse be made in the general form and arran ement of the several parts herein describe( without departing from the spirit and sco )e of my invention. Hence I do not wish te he limited to the exact construction herein set forth.

What I claim as new, and desire to secure by Letters Patent, is

l. A bottle-stopper comprising an inner and outer casing, a series of spiral corru ations on the inner casing, a plunger provicIed with a disk on the upper end thereof, adapted to operate in the inner casing, flanges on the upper and lower ends of said inner casing a apted to prevent the lunger from falling out of said inner casing, t e inner casing having openings on the lower end thereof allowing t e liquid in the bottle to flow into the channels formed by the cerrugations between lOO the inner and outenasing, substantially as described.

2. A bottle-stopper comprising an inner and outer easing, the inner easing having openings on the lower end thereof, a series of spiral corrugations on the inner easing leading into said openings, a plunger, provided with a disk on the upper end thereof, operating in the inner easing, flanges on the upper and lower ends of said easing adapted to prevent the plunger from falling out of the inner easing, substantially as described.

3. A bottle-stopper comprising an inner and outer easily, said inner easing having openings on the ower end thereof, a series of spiral eorrugations on the lnner easing leading` into said openin s, a lun er, provided on the up er end t ereo wit a convexshaped dis operating in the inner easing, sai plunger when in its downward position elosin the openings leading into the bottle and tus preventing the liquid from being forced into the bottle7 substantially as described.

In testi1nonT that I claim the foregoing as my invention l have si ned my naine in the presenee of two subseri ing witnesses.
